An eye is a hole inside your group

An 'eye' is an empty point fully surrounded by stones of one color — a tiny hole the opponent can never legally fill.

Which empty point is an eye for Black?

Start with the end in mind

What does winning look like?

Go is a quiet race for empty space. When neither player can gain more, the game ends and you count: each empty point you fully surrounded is a point. Most stones on the board never get captured — they just own land.

  • Stones draw the walls.
  • Empty points inside your wall are your territory.
  • More territory wins. Captures help, but territory decides.

Click Reveal territory on the board to see who won and why.

A finished 9×9 game. Empty points fully surrounded by one color become that color's territory.

Choose your path

Every path starts with placing one stone.
